			<li>
				Trying different scrollbar plugins,
				I wasn't able to find a lightweight and easy to use one,
				which is also touch friendly.
				<br />
				So I thought it's better to make one.
				<br />
				It's minimal but should be enough for most cases.
				<br />
				You can also use other more advanced plugins if necessary. There should be no conflicts.
			</li>
			<li>
				Here is a simple snippet which add vertical scrollbars to an element and limits its size to 400:
<pre data-language="javascript">
 $('#my-content').ace_scroll({size: 400});
</pre>
			</li>
 		 </ul>
		</div>
		
		<h3 class="info-title smaller">2. Options</h3>
		<div class="info-section">
		 <ul class="info-list list-unstyled">
					<li>
						<code>size</code> which is 200px by default
<pre data-language="javascript">
 $('#my-content').ace_scroll({size: 400});
</pre>

					You can also specify size using <code>data-size</code> attribute:
<pre data-language="html">
<div id="my-content" data-size="300">
   ...
</div>
</pre>
					</li>
					<li>
						<code>horizontal</code> default=false. If true, horizontal scrollbars will be added
<pre data-language="javascript">
$('#my-content').ace_scroll({horizontal: true});
</pre>
					</li>
					
					<li><code>mouseWheel</code> default=true. Scrolls content on mouse wheel event. When end of content is reached, mouse wheel event will be propagated to window</li>
					<li>
						<code>mouseWheelLock</code> default=false. If true and we have reached end of scrolling on our element, mouse wheel event won't be propagated to window
						<br />
						<code>lockAnyway</code> default=false. If true, even if scrollbars are not needed and are not visible yet, mouse wheel event won't be propagated to window
						<br />
<pre data-language="javascript">
 $('#my-content').ace_scroll({size: 300, mouseWheelLock: true});
</pre>
					</li>
					
					
					<li><code>styleClass</code> additional style classes you can add to scrollbars. See next section for more info.</li>
					
					<li>
						<code>hoverReset</code> default=true, because of window size changes and other document layout changes,
						content sizes may change and we may need to reset scrollbar size.
						<br />
						It can be done on mouseenter event, which is set to true by default.
					</li>
					
					<li>
						<code>reset</code> default=false. If true, content will be scrolled to 0, on initialization.
						<br />
						Does not work when the element is hidden at first.
					</li>
						
					<li>
						<code>dragEvent</code> default=false. If true an event will be triggered when
						user starts dragging scrollbars using mouse.
					</li>
					
					<li>
						<code>scrollEvent</code> default=false. If true an event will be triggered when
						content is scrolled.
					</li>

					<li>
						<code>touchDrag</code> default=true, which adds touch drag event for touch devices.
					</li>
					<!--
					<li>
						<code>touchSwipe</code> default=false, which adds touch swipe event instead of drag event.
					</li>
					-->

		<h3 class="info-title smaller">3. Styles</h3>
		<div class="info-section">
		 <ul class="info-list list-unstyled">
			<li>
				Some additional classes you can add using <code>styleClass</code> option:
				<ol>
					<li><code>scroll-margin</code> which add 1px space between content and scrollbars</li>
					<li><code>scroll-left</code> shows scrollbars on left instead of right</li>
					<li><code>scroll-top</code> shows horizontal scrollbars on top instead of bottom</li>
					<li><code>scroll-dark</code> darker scrollbars</li>
					<li><code>scroll-light</code> lighter scrollbars</li>
					<li><code>no-track</code> hides scroll track</li>
					<li><code>scroll-visible</code> scrollbars always visible</li>
					<li><code>scroll-thin</code> thinner scrollbars</li>
					<li><code>scroll-chrome</code> similar to latest version of Google Chrome scrollbars </li>
				</ol>
			</li>
			
			<li>
<pre data-language="javascript">
 $('#my-content').ace_scroll({
    size: 300,
    styleClass: 'scroll-dark scroll-left scroll-thin'
 });

 		 </ul>
		</div>
		
		
		
		<h3 class="info-title smaller">4. Events</h3>
		<div class="info-section">
		 <ul class="info-list list-unstyled">
			<li>
				If you set <code>scrollEvent</code> to true, a scroll event will be triggered when element is scrolled:
<pre data-language="javascript">
 $('#my-content')
 .ace_scroll({
    scrollEvent: true
 })
 .on('scroll', function() {
    //element scrolled
 });
</pre>
			
			But it's better to listen to the inner content's native scroll event:
<pre data-language="javascript">
 $('#my-content').find('.scroll-content').on('scroll', function() {
    //element scrolled
 });
</pre>
			</li>
			
			<li>
				If you set <code>dragEvent</code> to true, some drag events will be triggered when scrollbars are dragged:
<pre data-language="javascript">
 $('#my-content')
 .ace_scroll({
    dragEvents: true
 })
 .on('drag.start', function() {
    //started dragging
 })
 .on('drag._end', function() {
    //ended dragging
 })
</pre>
			</li>
 		 </ul>
		</div>
		
		
		<h3 class="info-title smaller" data-id="#custom/scrollbar.touch-drag">5. Touch Drag Event</h3>
		<!-- #section:custom/scrollbar.touch-drag -->
		<div class="info-section">
		 <ul class="info-list list-unstyled">
			<li>
				There is also a custom touch drag event specifically for use on scrollbars.
				<br />
				You can use it with other elements as well, though I recommend a more advanced library such as
				<b>Hammer.js</b>
			</li>
			
			<li>
				You can use it like this:
<pre data-language="javascript">
$('#some-element').on('ace_drag', function(event) {
  //var dir = event.direction;// up down left right
  //var distanceX = event.dx 
  //var distanceY = event.dy
})
</pre>

		<h3 class="info-title smaller">6. Functions</h3>
		<div class="info-section">
		 <ul class="info-list list-unstyled">
			<li>
				The following functions are available for scroller plugin:
				<ol>
					<li><code>reset</code> resets scrollbar size</li>
					<li><code>disable</code> disables scrollbars</li>
					<li><code>enable</code> enables scrollbars</li>
					<li><code>destroy</code> destroys scrollbars</li>
					<li><code>update</code> updates an option (currently only size)</li>
					<li><code>modify</code> updates options and recreates scrollbars</li>
				</ol>
			</li>
			
			<li>
<pre data-language="javascript">
$('#my-content').ace_scroll('reset');
$('#my-content').ace_scroll('disable');

$('#my-content').ace_scroll('update', {size: 250});
$('#my-content').ace_scroll('modify', completely_new_options);
</pre>
			</li>
 		 </ul>
		</div>


		<h3 class="info-title smaller" data-id="#custom/scrollbar.horizontal">7. Horizontal</h3>
		<!-- #section:custom/scrollbar.horizontal -->
		<div class="info-section">
		 <ul class="info-list list-unstyled">
			<li>
				Horizontal scrollbars can be created by specifying <code>horizontal</code> option:
<pre data-language="javascript">
$('#my-content').ace_scroll({
    horizontal: true,
    size: 600,
    styleClass: 'scroll-top',
    mouseWheelLock: true
});
</pre>
			</li>
			
			<li>
				Sometimes you may need to add some padding to the element if scrollbars appear above content:
<pre data-language="javascript">
$('#my-content').ace_scroll({
    horizontal: true,
    //options here
}).css('padding-top', 15);
</pre>
			</li>
			
			<li>
				If you are using RTL (right to left) direction,
				please note that horizontal scrolling is inconsistent between browsers.
				<br />
				So it's better to change scrollbars to LTR and make the content RTL again.
				<br />
				You can use <code>.make-ltr</code> and <code>.make-rtl</code> classes:
				<br />
				
<pre data-language="javascript">
 $('#my-content').addClass('make-ltr')
 .find('.scroll-content').wrapInner('&lt;div class="make-rtl" /&gt;');
</pre>
			</li>
			
			Or statically inside your HTML:
<pre data-language="html">
 <div id="my-content" class="make-ltr">
   <div class="make-rtl">
     ...
   </div>
 </div>
</pre>
<pre data-language="javascript">
$('#my-content').ace_scroll({
    horizontal: true,
    //other options here
})
</pre>
			</li>

 		 </ul>

		<h3 class="info-title smaller" data-id="#custom/scrollbar.sidebar">8. Sidebar Scrollbars</h3>
		<!-- #section:custom/scrollbar.sidebar -->
		<div class="info-section">
		 <ul class="info-list list-unstyled">
			<li>
				You can also use scrollbar for sidebar whether it's fixed or not.
			</li>
			
			<li>
				I have used two approaches for sidebar
			</li>
			
			<li>
				The first one which is used by default, does not use <code>overflow:hidden</code> and
				can be used only on fixed sidebar.
				<br />
				The advantage is that .hover submenus or mininized sidebar can also have scrollbars and
				submenus will be shown outside of sidebar area without problem.
			</li>
			
			</li>
				Second one uses real scrollbars and has <code>overflow:hidden</code> applied to it.
				<br />
				It can be used on both normal and fixed sidebar.
				<br />
				To enable it you should <a href="../build/js.html">build a custom JS</a> using 2nd sidebar scrollbar style.
			</li>
			
			<li>
				Each one has several options which you can edit inside:
				<ol>
					<li><code>assets/js/ace/ace.js</code></li>
					<li><code>assets/js/ace.min.js</code></li>
					<li><code>assets/js/uncompressed/ace.js</code></li>
				</ol>
				<br />
				Look for <code>sidebar_scrollable</code> and change options as needed.
			</li>
			
			<li>
				Options for first style (fixed sidebar only):
				<ol>
				  <li><code>scroll_to_active</code> If true, sidebar will be scrolled down to show active menu item on page load</li>
				  <li><code>include_shortcuts</code> If true, shortcuts will also be inside scroll area. Otherwise it will be above scroll area</li>
				  <li><code>include_toggle</code> If true, sidebar toggle(minimize button) will also be inside scroll area. Otherwise it will be below scroll area</li>
				  <li><code>smooth_scroll</code> If true, sidebar scrolling will be smooth using CSS3 transition</li>
				  <li><code>outside</code> If true, scrollbar will be outside of scroll area</li>
				</ol>
			</li>
			
			<li>
				Options for secod style (normal/fixed sidebar):
				<ol>
				  <li><code>only_fixed</code> If true, scrollbars will be enabled for fixed sidebar only</li>
				  <li><code>scroll_to_active</code> If true, sidebar will be scrolled down to show active menu item on page load</li>
				  <li><code>include_shortcuts</code> If true, shortcuts will also be inside scroll area. Otherwise it will be above scroll area</li>
				  <li><code>include_toggle</code> If true, sidebar toggle(minimize button) will also be inside scroll area. Otherwise it will be below scroll area</li>
				</ol>
